Description

Technical Field

[0001] The utility model relates to the technical field of automobile auxiliary parts, and more specifically, to a portable engine ECU fixing bracket for assembling and disassembling. Background Art

[0002] The engine ECU is a key component for controlling the engine in a car. In addition to controlling the engine operation, the ECU also has the function of protecting the engine and the car's safety. The ECU is generally arranged on the longitudinal beam at the front of the car body and needs to be connected to the longitudinal beam of the car body through the ECU mounting bracket.

[0003] According to the existing ECU fixing bracket in the disclosed technology, bolts are generally used to fix the ECU to the surface of the frame. During the ECU removal process, if the bolts or the surface of the frame are not handled carefully, they may be damaged. After the ECU is removed, the bolt holes and the surface of the frame need to be cleaned to ensure a firm connection during the next installation, which increases the complexity and time cost of the maintenance process. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a portable engine ECU fixing bracket for assembly and disassembly, which has the advantages of easy assembly and disassembly.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable engine ECU fixing bracket for assembly and disassembly, comprising an assembly seat and a bracket body, limit plates are fixedly installed on both sides of the front of the assembly seat, quick-connect seats are fixedly installed on the upper and lower sides of the front of the limit plates, a shrinking cylinder is fixedly installed inside the quick-connect seat, a return spring is movably installed inside the shrinking cylinder, a positioning rod is movably installed inside the shrinking cylinder, a spherical chamfer is provided at the bottom of the positioning rod, a top plate is fixedly installed on the top of the surface of the positioning rod, slide grooves are provided on both sides of the front of the bracket body, one end of the slide groove is provided with a chamfer, a positioning hole is provided on one side of the bottom of the slide groove, a chamfer is provided at the edge of the positioning hole, and the position of the positioning hole is matched with the position of the shrinking cylinder.

[0009] As a preferred technical solution of the utility model, a shock-absorbing pad is fixedly installed on the top of the bracket body, and a plurality of through grooves are provided on both sides of the bracket body.

[0010] As a preferred technical solution of the present utility model, a card slot is provided on the inner side of the limiting plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model simplifies the steps of separating the ECU from the vehicle through the design of the overall structure, thereby making the installation and removal of the ECU bracket simple and quick.

[0023] Among them, through the design of the overall structure, the function of simplifying the steps of separating the ECU from the vehicle is achieved, thereby making the installation and removal of the ECU bracket simple and quick. When replacing or repairing the ECU at a later time, the user can easily fix or remove the bracket, reducing parking time and labor costs.

[0024] A plurality of limiting grooves 11 are formed on the surface of the shrinking tube 5 , and a plurality of connecting blocks 12 are fixedly mounted on the inner circle of the top plate 8 . The connecting blocks 12 are fixedly connected to the positioning rods 7 .

[0025] Among them, the limiting groove 11 is used to provide moving space for the connecting block 12, so as to avoid the ECU from shaking during the driving of the vehicle, which may cause the internal electrical components to loosen. The connecting block 12 is used to connect the top plate 8 with the positioning rod 7, so that the positioning rod 7 drives the top plate 8 to move synchronously, and then the deformable characteristics of the return spring 6 are used to degrade the vibration or impact force during the driving of the vehicle, reduce the transmission of vibration or impact force between the assembly seat 1 and the bracket body 2, and thus increase the service life of the ECU.

[0026] First mounting holes 13 are provided on both sides of the top of the mounting seat 1 , and second mounting holes 14 are fixedly installed at both corners of the bottom of the mounting seat 1 .

[0027] The first mounting hole 13 and the second mounting hole 14 facilitate the mounting of the mounting base 1 to the vehicle frame, and the mounting base 1 is fixed at multiple points, thereby increasing the stability of the mounting base 1 .

[0028] A cable harness hole 15 is provided at the top of the front side of the bracket body 2 , and connection holes 16 are provided at the four corners of the front side of the bracket body 2 .

[0029] Among them, the wiring hole 15 facilitates the concentration of the ECU connecting wires and passes through the bracket body 2, the connecting hole 16 facilitates the installation of fixing bolts to connect the ECU to the bracket body 2, and the shock-absorbing pad 17 facilitates the reduction of vibration or impact force transmission between the bracket body 2 and the ECU, further increasing the service life of the ECU.

[0030] A shock-absorbing pad 17 is fixedly mounted on the top of the bracket body 2 , and a plurality of through slots 18 are formed on both sides of the bracket body 2 .

[0031] The through slot 18 can be used to reduce the weight of the bracket body 2 while maintaining sufficient structural strength and stability.

[0032] A clamping slot 19 is formed on the inner side of the limiting plate 3 .

[0033] The card slot 19 is used to provide a space for accommodating the bracket body 2 and to limit its position.

[0034] The working principle and use process of the utility model are as follows: when installing the ECU, the fixing bolts are installed through the first mounting hole 13 and the second mounting hole 14 to fix the assembly seat 1 to the appropriate position of the vehicle frame, and the fixing bolts are installed through the connecting hole 16 to connect the ECU to the bracket body 2, and the ECU connecting wire harness is concentrated through the bracket body 2 through the harness hole 15, and the bracket body 2 is inserted into the bracket body 2 through the top opening of the slot 19. During this period, the bracket body 2 is limited by the positioning rod 7 in cooperation with the slide groove 9, and the positioning rod 7 is gradually provided with thrust through the chamfer of the slide groove 9. The spherical chamfer at the bottom of the positioning rod 7 cooperates with the chamfer at the bottom of the slide groove 9 to provide guidance. When the positioning rod 7 enters the inside of the slide groove 9, the slide groove 9 pushes the positioning rod 7, and the positioning rod 7 slides in the internal cavity of the shrink tube 5. At the same time, the positioning rod 7 releases the thrust to the top plate 8 through the connecting block 12, and the reset spring 6 is compressed by the top plate 8. After receiving the pressure, the reset spring 6 is deformed to absorb the pressure, and the bracket body 2 is pushed to the slot 19 When the ECU is removed, the two sides of the bracket body 2 are held, and the resistance is provided by the through groove 18 to cooperate with the user to generate an upward traction force. Before the bracket body 2 receives the traction force and slides upward, the spherical fillet at the bottom of the positioning rod 7 cooperates with the chamfer at the edge of the positioning hole 10 to provide a guide, gradually generating a thrust on the positioning rod 7. The positioning rod 7 compresses the reset spring 6 again through the top plate 8. After the reset spring 6 receives the pressure, it deforms to absorb the pressure, and the bracket body 2 can be taken out. In the above-mentioned working process, the user only needs to push and pull the bracket body 2 to complete the connection or disconnection between the ECU and the vehicle.
